5PEGIFICATION forming part of Letters Patent No. 347,961, dated August24, 1886.

Application filed April 23, 1583. Serial No. 92,623. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE H. SAOKETT, of Brooklyn, in the county ofKings and State of New York, have invented an Improvement inFountain-Pens, of which the following is a specification.

This invention relates to that class of writing implements in which inkis automatically supplied to the pen from a reservoir or hollow holder,and which are commonly termed fountaiirpens.

Its object is to provide for the facile transmission of the ink from theholder to the pen without the aid of the special devices commonlyemployed and considered necessary for such purpose. To this end itcomprises a novel construction of a fountain-pen with a holder closed atits upper or outer end, and having a suitable opening atitslowerextremity, and a slitted writing-pen having its slit carried upward in.immediate communication with the ink-space of said reservoir, in suchmanner that the volume of ink being in direct contact with the inner endof the slit insures the action of the latter as a channel or conduit toconduct the requisite current of ink to the point of the pen during theoperation of writing, thereby dispensing, as hereinbel'oreindieated,with the special devices or appliances heretofore considered necessaryin this class of Writing implements.

Figure 1 is a back view, 011 an enlarged scale, of a fountain-penembracing my said invention. Fig. 2 is a side view and partial sectionof the same. Fig. 3 is a cross-section thereof, taken in the line 00 wof Figs. 1 and 2 Figs. 4, 5, and 6 are like views of a pen, showing amodification of my said invention. Fig. 7 is a longitudinal sectionalview, still further illustrating my said invention. Fig. 8 is a viewfrom the under side, and Fig. 9 a transverse sectional view in the line00 x of Fig. 8, showing another modification of my said invention. Figs.10 and 11 are corresponding views of another modification of my saidinvention.

Referring first to Figs. 1, 2, and 3, A is the reservoir, which ishollow or tubular and closed at its upper or outer end, as shown at a,and open at its lower end. This construction of the reservoir is commonto the several modifications of my said invention. To the lower end ofsaid holder is provided the pen B.

As shown in Figs. 1, 2, and 3 aforesaid, the pen is formed in one piecewith the hollow reservoir A, very much as a pen is provided upon thetubular portion of a quill on the well-known quill pen; but in thepresent case the slit 0 is carried inward or upward until its inner endcommunicates with the interior of the tubular reservoir Athat is to say,with the ink-reservoir contained or provided therein. The inksustainedin the saidreservoir by atmospheric pressure from below passes,

by capillary attraction, direct to said slit, and

as the ink is exhausted from the point of the pen in the operation ofwriting a constant flow to and along the said slit is secured, therebyproviding the requisite supply to the point of the pen so long as theoperation of writing is continued, and this without'the aid of anyadditional mechanical device to conduct the ink to the slit, and thenceto the point of the pen.

Having reference to Figs. 4,5, and 6, the pen Bis thrust bodily into theopen lower end of the reservoir A, its edges fitting into grooves orrecesses provided for their reception in the interior surface of thereservoir, the pen being thus held in position with its slit 0 extendedupward or inward,with its inner extremity in such relation with thespace occupied by the ink that the latter maypass directly into theinner portion of the slit 0, and be thence transmitted to the point ofthe pen.

\Vhen desired, the reservoir A may, for convenience in filling andchanging pens, be made in two parts, d c, screwed together, as shown inFigs. 4 and 5, the lower one constituting a socket, in whiehthe pen isinserted in position and relation to the ink-reservoir as hereinbeforeexplained.

Having reference to Fig. 7, in this modification the pen B is inserteddirectly within the open lower end of the hollow reservoir A,substantially as described with reference to Figs. 4, 5, and 6.Extending inward from the pen, and preferably attached thereto, or, ifdesired, integral therewith, as represented in said figure, is aninwardly-projecting tongue, f, which constitutes a feeding-stem, andwhich, by the additional surface presented to the ink within thereservoir, provides an additional means for directing the ink downwardwithin the reservoir to the inner end of the slit of the pen.

Having reference to Figs. 8 and 9, the pen is formed in one with theholder, as in Figs. 1, 2, and 3, except that instead of being formed atthe upper side of the reservoir it is provided at the lowerside, whichis made concave in cross-section, as shown in Fig. 9, the ink passing tothe slit of the pen (said slit being extendedinto the ink-reservoir, asin the other modifications of my said invention) at the back or upperside of the latter, and thence through said slit to the point.

Having reference to Figs. 10 and 11, the pen is arranged at the underside of the reservoir in substantially the same relation therewith as inFigs. 8 and 9, with this modification, that the under side of the lowerend of the reservoir is formed into a socket to receive the innerportion of the pen, and is formed with a,

longitudinal slot, 0, coincident with the slit of the pen, which saidslot, in fact, forms part of the ink-reservoir thereof, and which is soarranged that the ink may pass readily therefrom to and into the innerend of said slit, and thence to the point of the pen, as in the othermodification, hereinbefore described, of my said invention.

It is to be observed that in order to insure the hereiirdescribedfeeding-action of the slit 0 of the pen it is requisite that the back ofthe pen should be of such thickness that the opposing flat surfaces ofsaid slit shall afford substantial adhesive attraction to the ink inother words, a substantially capillary attraction, which will insure theflow of theink downward from the top of the slit as fast as the same isexhausted from the bottom thereof. This thickness of the pen may bevaried within wide limits, but may be stated, in genera], as twice thatof an ordinary steel pen, or, if desired, considerably more; in some instances, perhaps, a little less.

\Vhen desired, the opening at the lower end of the holder or reservoirmay be in duplicate, as shown in Fig. 12--iu other words, may be dividedinto two compartments, into one of which the pen may beinserted andsecured, as shown in said figure.

.the drawings, the whole reservoir is closed at its upper end and openat its lower end, air being admitted through the opening at the lowerend to supply the place of theink withdrawn from the reservoir in theact or operation of writing. It will further be observed that when anair'tube is used to permit the inflow of air at the lower end of thereservoir, as aforesaid, the opening formed directly in the lower endmay be proportionally diminished, to simply permit the flow of ink tothe pen.

What I claim as my invention is- 1. The combination, with the reservoirof afountain-pen, closed throughout, except at its permanently-openlower end, of a slitted pen, the slit whereof extends from the point ofthe pen upward or inward to or into the said open lower end of thereservoir, to form the channel for the passage of the ink from said openlower end to the point of the pen, substantially as and for the purposeherein set forth.

2. A reservoir or tubular holder constructed with longitudinal groovesin the inner walls of its lower end, in combination with a pen thelateral edges of which fitinto said grooves, thereby insuring theretention of the pen in place, substantially as and for the purposeherein set forth.

3. The combination, with the reservoir of a fountain-pen, closedthroughout, except at its permanently-open lower end, of an internalfeeding-stem fixed in its relation with the said reservoir, andarraugedto assist the flow of ink downward in the said reservoir to feedthe ink toward the pen in the act of writing, and to aid in filling thepen when the reservoir is reversed, substantially as and for the purposeherein set forth.
